什么是$之间的区别，并获得$发现在JavaScript中？ [英] What's the difference between $get and $find in JavaScript?

问题描述

我是谁才刚刚开始了解客户端脚本一个.NET程序员，我在想，有时你使用 $ GET（'值'）和 $找到（'值'）键，我发现，这些只是为的document.getElementById（'值'）和<一个href=\"http://msdn.microsoft.com/en-us/library/bb397522%28loband%29.aspx\"><$c$c>Sys.Application.findComponent('value'),分别。

I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value'), respectively.

不过，我还是不明白：什么是JavaScript中这两个函数之间的区别？究竟什么是调用时查找/检索？

However, I still don't understand: what is the difference between these two functions in JavaScript? What exactly are they looking up/retrieving when invoked?

先谢谢了。

推荐答案

$ GET ＆安培; $找到的快捷功能微软已经内置到他们的Ajax JavaScript库。

$get & $find are shortcut functions Microsoft has built into their Ajax JavaScript Library.

$ GET 是短期的标准JavaScript 的getElementById 功能。 $找到是短期的。NET的<一个href=\"http://www.asp.net/ajax/documentation/live/clientreference/Sys/ApplicationClass/SysApplicationFindComponentMethod.aspx\"><$c$c>findComponent()功能。这不是一个标准的JavaScript功能，是专门针对微软的Ajax JavaScript库。

$get is short for the standard JavaScript GetElementById function. $find is short for .Net's findComponent() function. This is not a standard JavaScript function and is specific to Microsoft's Ajax JavaScript library.
